Prevalence of Antibody against Hepatitis A in Sweden in Relation to Age and Type of Community

Abstract
In 1968 sera collected from persons selected on a statistical basis, as a representative sample of the Swedish population, were tested for antibody against hepatitis A (anti-HAV). The prevalence of anti-HAV increased with age from 4% (3/83) among 15-19 yr old''s (born between 1948 and 1952) to 87% (68/78) among 60-69 yr old''s (born between 1898 and 1907) and was higher in cities than in rural areas for corresponding age groups.
